Here’s a basic example of a Kotlin code snippet for displaying a “Hello, World!” message in an Android app:
import android. Os. Bundle
import android. Widget. TextView
import androidx. Appcompat. App. AppCompatActivity class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super. OnCreate(savedInstanceState) setContentView(R. Layout. Activity_main) val textView = findViewById<TextView>(R. Id. TextView) textView. Text = "Hello, World!" }
}
This code demonstrates how to set the text of a TextView in an Android app. Mobile app developers use such code to build complex and interactive mobile applications.
